Yikes, Scooby Doo the cowardly pup with the voracious appetite suddenly finds himself in a tricky situation. Shaggy, Velma, Daphne, Fred and Scoob are driving along in the beaten up Mystery Mobile when a strange rattling beneath the bonnet forces them to pull over to see what's wrong. "It's no good," said Freddie "we'll have to get help from somewhere." "What about that big castle over there?" said Velma pointing to a dark gothic house silhouetted against the moon. "We could knock at the door and ask them if there's a garage or something nearby." she continued. "Yeah, that's fine, like Scooby and I will er wait in the van in case someone tries to uhh, steal it, right Scoob?" said Shaggy, looking distinctly nervous. "No, all four of us will go and Scooby can stay behind in the van," said Velma. And the four of them started walking towards the dark forbidding looking castle, leaving Scooby sleeping in the back of the Mystery Mobile.
Little do they know but the castle on the hill is owned by a mad professor who likes nothing more than to lure victims back to his deserted lab and chop them up into little pieces and store them in specimen jars for future experiments. Double yikes!
And surprise, surprise that's exactly what happens to Shaggy, Velma, Daphne and Fred. That dastardly professor ensnares the gang in his evil plan and leaves them, apparently trapped forever in his draughty, lonely castle.
And they'd still be there now if it wasn't for that canine coward Scooby Doo behaving in most uncharacteristic manner and trying to release his pals from their predicament. Perhaps it was hunger that drove Scooby from the beaten up van, or maybe the eerie way the wind moaned around the roof. Whatever it was, Scooby decided to see what was going on inside the castle...
However, when Scooby enters the professor's castle he has a shock in store for him. The castle seems to be haunted by all manner of nasty spooks and ghosties. He's about to run back to the van for all he's worth when he spots a Scooby Snack on the ground and realises that his friends must be in mortal danger.
There are four levels to the game and concealed on each level is one member of the gang trapped inside a specimen jar. Scooby has to locate his chums and release them.
However, Scooby Doo encounters a strange array of beasties on each of the levels and they are all determined to stop him from releasing his friends. And of course these nasties are all controlled by the evil professor himself.
On the first floor of the castle - which contains Velma - Scooby encounters horrible floating ghoulies which jump out from behind closed doors and are very menacing to the poor pooch. Hooded figures sidle up to him silently and try and knock him off his paws. The only way which Scooby can defend himself against the nasty inhabitants of this castle is by using his cumbersome paws which come in very handy for bopping the spectres on the bounce. Scooby can only hit his victims if he's not moving, and if they get him first he faints with fear and loses one of his six lives. When all these lives have been lost Scooby joins his friends as a future experiment for the professor. Evil cackle. However, Scooby can reclaim a lost life by picking up a Scooby Snack on the ground and eating it.
Level two of the castle is full of springy, sproingy things. These bounce out of cupboards and dumb waiters and sneak up on the dynamic doggy from behind. Skulls litter the floor and must be bounced over and floors are separated by ladders which must be climbed. But be careful ... the nasties have a habit of scooting down the stairs and knocking poor Scoob for six. Level three hosts some very wicked looking monsters. Ghoulfish float around exercising their huge elastic jaws. The ghosties from the first level make a re-appearance, and tatty bats screech around at head height causing Scooby to bend down and cover his eyes with fright!
The final level is guarded by bulbous monks with no faces. Flying dumbells and rolling bowling balls are just some of the hazards which Scooby has to negotiate in the quest to release the last of his chums.
At the beginning of each level Scooby gains an extra life, but lives lost in the previous level are not given back to him ... For once, this hungry dog gets the chance to play the hero.
